Short-channel and high-mobility p- and n-type organic single-crystal transistors with air-gap structures
In an effort to realize high-speed organic logic components, p- and n-type single-crystal organic field-effect transistors (SC-OFETs) were fabricated using air-gap structures with channel lengths as short as s...
